Fig. 5.
Left: phase coverage as a function of the orbital period of an hypothetical planet around the target pcrSp0643-1843 (chosen arbitrarily), observed for 134.3 h in total by SPECULOOS. Right: graphic visualisation of the coverage of target pcrSp0643-1843 for an orbital period of 4.7 days. Each blue circular arc represents one night of observation; its size is proportional to the number of hours observed each night and the full circle depicts a duration of 4.7 days.
